Substantial quakes accompanied by tsunami have actually taken place in the Ocean of Japan off north with central Japan. Contaminated products in fish examined A group of Oriental analysts are researching fish organs to predict exactly how long contaminated products will certainly stay in fish caught in waters off the Fukushima Daiichi nuclear plant.

Can Dental Anesthetic Really Make Your Heart Beat Faster?
Back when I was in dental school, the instructors told us to always pull back on the anesthetic syringe before injecting. By doing this, we would make sure that we weren't injecting the anesthetic into a blood vessel, which would cause the epinephrine in the anesthetic to make the patient's heart feel like it was beating out of their chest.
They called this the epinephrine reaction, and I blindly believed it. I even wrote a post about why dental anesthetic makes your heart beat faster. Until one day, this belief was questioned by a comment on that article (which actually caused Gavin to post a rather entertaining comment). I realized that I'd blindly believed what I'd been taught without doing any research of my own.
In this follow-up article, I'll answer the question: Can dental anesthetic really make your heart beat faster?
A few weeks ago, a woman told me that she hates getting injections because it makes her heart beat really fast. I asked her if a dentist had ever offered her the anesthetic brand Carbocaine (a type of dental anesthetic without any added epinephrine). She told me that she'd never heard of it. I tried it on her and she told me that it was the first injection she could remember where she didn't feel like her heart was beating out of her chest.
Naturally, this (along with other similar experiences) made me a believer that regular dental anesthetic with epinephrine can indeed make your heart beat faster. As a dentist I realize that stories, while fun and exciting, may not be a very good source of evidence, so I decided to do some more in-depth research.
Can Dental Anesthetic Really Make Your Heart Beat Faster?
The main question here is whether or not the small amount of epinephrine inside the dental anesthetic makes your heart beat faster or if it's simply caused by the epinephrine your body releases in response to being afraid of the crazy dentist that's about to poke you.
Many years ago, it was thought that the tiny amount of epinephrine in the dental anesthetic made no difference in your heart rate, and any change in your heart rate was simply caused by the "fight or flight" response.
Many studies have since confirmed that the epinephrine in dental anesthetic can cause an increase in your heart rate.
One study states that "intravenous administration of 0.015 mg of epinephrine with lidocaine results in increase in the heart rate ranging from 25 to 70 beats per minute, with elevations in the systolic blood from 20 to 70 mm Hg." For your information, one cartridge of dental anesthetic contains 0.018 mg of epinephrine — that's even more than the amount that has been shown to increase the heart rate by 25 to 70 beats per minute. Here's a link to one of those studies that discusses this.
Malamed's dental textbook on anesthetic even confirms what I'd discovered. It says, "Contrary to a previously held position that the intraoral administration of "usual" volumes of epinephrine produced no cardiovascular response and that patients were more at risk from endogenously released epinephrine than they were from exogenously administered epinephrine, recent evidence demonstrates that epinephrine plasma levels equivalent to those achieved during moderate to heavy exercise may occur after intraoral injection."
That simply says that the epinephrine in dental anesthetic can make your heart beat very fast, even tricking it into beating as fast as it would if you were exercising.
The author goes on to state that even if your dentist does inject slowly and "pull back" to ensure that they don't inject into a blood vessel, your heart can still beat faster: "However, even following usual precautions (e.g. aspiration, slow injection), sufficient epinephrine can be absorbed to cause sympathomimetic reactions such as aprehension, tachycardia, sweating, and pounding in the chest (palpitation): the so-called "epinephrine reaction."
More Evidence That Dental Anesthetic Can Make Your Heart Beat Faster
Even more evidence that dental anesthetic can make your heart beat faster comes from the American Heart Association. They recommend that any patients with heart disease receive a maximum of 0.04 mg of epinephrine from dental anesthetic. That's usually the equivalent of just two cartridges of dental anesthetic. For comparison's sake, a normal person without heart disease can receive up to eleven cartridges of anesthetic.
This shows that the AHA believes that the epinephrine in dental anesthetic can have an effect on the heart, and that's why they recommend limiting it so strictly.
The textbook Dental Management of the Medically Compromised Patient confirms this by stating "If [a vasoconstrictor] is considered essential, use cautiously (maximum 0.036 mg epinephrine or 0.20 mg levonordefrin)." Levonordefrin is similar to epinephrine, but it is mostly used in European countries, not in the U.S.
Lastly, the American Acamedy of Pediatric Dentists even has guidelines for dentists telling us what to do when a patient has a reaction to the epinephrine in dental anesthetic. They say to reassure the patient, ensure they're breathing well, and to check their vital signs if necessary.
Dental Anesthetic Can Make Your Heart Beat Faster
In summary, the most recent studies and evidence all point to the fact that the epinephrine (or levonordefrin for my European friends) can definitely make your heart feel like its beating out of your chest!

Turkey Day Tips For Keeping Your Smile Healthy And Happy

Thanksgiving is here and it’s time for family and, of course, food. Most of the food that is served at Thanksgiving is loaded with sugars and carbohydrates. This can give your healthy smile some grief, but there are some adjustments you can make that will help keep your teeth healthy.
The carbohydrates in stuffing, dinner rolls and the desserts induce acid production in your mouth. Acid from this bacteria is responsible for tooth decay. You can protect yourself from these acids by following these simple tips:

Myths About Root Canals Busted
| Root canal therapy is widely considered to be the dental procedure that is most feared. This unfounded fear is usually based on someone else’s experiences and not their own. These fears, along with misinformation sometimes leads patients to request a tooth be extracted, rather than saving it with a root canal.
Root canal therapy is almost always performed because a tooth is causing a patient pain, and the condition is irreversible. The most likely conditions are Pulpitis, infected pulp, broken teeth or a dying nerve.
Most people think that root canal therapy is painful, but it is done to alleviate pain. Most patients report that the procedure did not cause pain and actually felt better afterwards.
Root canal therapy is usually completed in one or two visits. Sometimes more appointments are needed if the infection is extensive, if the root canal is extremely difficult or if a referral to a root canal specialist (endodontist) becomes necessary.
It has even been rumored that root canal therapy causes illness. This myth goes back to a study done by Dr. Weston Price from 1910-1930. Research that is almost 100 years old and has since been proven inaccurate.
If you think you need a root canal, don’t be afraid. Instead, get an examination by your dentist. If a root canal is recommended, be confident in knowing it will alleviate your discomfort.

Five Reasons to Go to the Dentist This Year
It's been estimated that half of all Americans don't go to the dentist regularly. If you find yourself in that half, how about making a New Year's resolution to make it to the dentist this year?
Here are five good reasons why you should.
Five Reasons to Go to the Dentist
1 - Catch Problems While They're Small
If you regularly visit the dentist, your dentist will be able to tell you about smaller problems that you can easily and inexpensively get fixed. The quicker you get a cavity filled, for example, the longer the filling will last. If you put off getting a cavity filled while it's small, it could cost significantly more to get it fixed when it needs a root canal and crown a few years down the road.
You won't feel any symptoms with most dental problems until they are advanced. If you have gum disease, it's important that you get it treated. However, unless you develop a gum abscess or have gum disease that is at a very advanced stage, you likely won't experience any pain.
2 - Dental Care Is Better Than It Was In the Past
If you had a bad experience in the past, let me assure you that dentistry has come a long way. There have been many recent advancements in the kinds of materials that we can use to fix your teeth. Many modern restorations such as crowns and veneers look completely natural and can give you the kind of smile you've always wanted.
3 - There Are Ways to Alleviate Dental Fear
There are many drugs that you can take before you go to the dentist to make you drowsy so that you will be less anxious during your procedure.
Also, if needles frighten you, many dentists can fill small cavities using a laser without any anesthetic. If you do require an anesthetic, there are very strong topical gels that can be placed on your gums before the injection to make the injection nearly painless.
We've come a long way since the dark ages when dentists were a little crazy — check out these pictures of old school dentistry if you don't believe me.
4 - There Are Better Deals Due to the Economy
Many dentists are running new patient specials due to the fragile state of the economy. They figure it's better to get a new patient in even if they charge a really low price than to have empty slots.
If you perform an internet search with the terms "dentist the name of your city", you will likely find some good deals that will allow you to have a free or low-cost exam and x-rays to get an overall idea of your general dental health.
5 - There are Financing Options Available
Also due to the economy, some dental offices are willing to accept payments for dental work performed rather than requiring the full amount at the time of service.
Another excellent option that we offer at my practice is called Care Credit. This allows patients to have the dental work performed and then make 12 equal, monthly payments over the course of the year without paying any interest. If you do go this route, just make sure that you make all of your payments on time. If you don't pay on time, then they will charge interest, which is how they make a lot of their money.
There's No Time Like The Present
If you've made it this far, go ahead and make that appointment! If you're hesitant to make a dental appointment, feel free to leave a comment below and let me know why. I'll try to get back to you and resolve any concerns you might have.
Have a great year!
